[0002] The traditional rotary Stirling refrigerator mainly realizes the reciprocating linear motion of the compression piston and the push piston through the drive of the rotary motor and the transmission of the crank-link mechanism. The vertical distribution in space will cause the refrigerator to waste space in the system application, which is not conducive to the micro-integration of the system

The invention provides a Stirling refrigerator, which comprises a base and a cold finger. A cold accumulator is arranged inside the cold finger. The base and the cold finger enclose a sealed cavity. The base is provided with a cam rotating part and drives the cam to rotate. The rotating motor rotates the cam rotating member. The outer wall of the cam rotating member includes a wavy mating surface arranged along the rotating direction of the cam rotating member. There are several synchronously working compression assemblies arranged in the base, and each of the compression assemblies is arranged around the mating surface. Each of the compression assemblies includes a cylinder, a piston and a piston push rod that cooperates with the mating surface to make the piston reciprocate in the cylinder, and each of the cylinders communicates with the cold finger. The present invention adopts a new transmission method that converts the rotary motion of the rotary motor M into the reciprocating linear motion of the piston, does not need to set up a crank-link mechanism, greatly reduces the volume of the refrigerant, and realizes the miniaturization and integration of the refrigerant. In addition, the compression components are evenly and oppositely distributed, which realizes the low vibration requirement of the refrigerant.
Description
technical field [0001] The invention relates to the field of refrigeration and cryogenic engineering, in particular to a Stirling refrigerator. Background technique [0002] The traditional rotary Stirling refrigerator mainly realizes the reciprocating linear motion of the compression piston and the push piston through the drive of the rotary motor and the transmission of the crank-link mechanism. If they are vertically distributed in space, the refrigerators will waste space in the system application, which is not conducive to the micro-integration of the system. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art and provide a Stirling refrigerator to realize low vibration, miniaturization and integration of the refrigerator. [0004] The present invention is achieved like this: [0005] The invention provides a Stirling refrigerator, which comprises a base and a cold finger. A cold accumulator is arranged ...
